From certain angles you can barely see this beautiful bicycle—because it's made from the same strong, lighthtweight and transparent plastic used in fighter jet canopies. It's the perfect stealth bike.

A concept put together by Designaffairs, this bicycle—aptly called Clarity Bike—is built from a polymer called Trivex. First used in helicopter windscreens and then in fighter jet canopies, the material is incredibly light but can withstand major shocks. It's also resistant to extremes of heat and cold, and can be injection moulded—so it would be perfect for making a bicycle. Designaffairs explain:

We believe that the Clarity Bike could be a giant leap forward in bicycle frame engineering and production. The design takes advantage of an advanced polymer which combines high impact resistance, lightweight properties and a gentle flexibility that usually would only be expected on an old Italian steel frame.

If this thing could be made affordably, they could sell an absolute ton—and I, for one, would be at the front of the queue. [Designaffairs via Dezeen]
